in the case of wire fabrics now on the market;

These being among the objects of the present invention, the sameconsists of certain features of construction and combinations of partsto be hereinafter described and then claimed with reference to theaccompanying drawings showing preferred embodiments of the invention andin which:

Fig. 1 is a plan of one form of the improved wire fabric;

Fig. 2 is a plan of one kind of link;

Fig. 3 is a section on the line 33, Fig. 2;

Fig. 4 is a planpf another kind of link used in the same fabric;

Fig. 5 is an edge view of the same link;

Fig. 6 is a section thereof onv the line 66, so Fig. 4;

Fig. 7 is a plan of anotherform of wire fabric;

-Fig. 8 is a plan of one kind of link used therein I Fig. 9 is a sectionthereof on the line 99, Fig. 8;

Fig. 10 is a plan of another kind of link used in the same fabric andFig. 11 is a section thereof on the line 11-41., Fig. 10.

Referring to Figs. 1 to 6 inclusive, the side rails 12, 13 are partiallyshown and one of the end rails 14 of the frame for supporting the wirefabric. Fabric tensioning springs 15,

16 are respectively connected with side rails 12, 13, the springs 15carrying rings 17. The wire fabric of the present invention may beconstructed as follows:

The fabric comprises alternate rows 18 of spaced links of one kind, eachlink of the end 21.

members of each link 28, at the extreme e1 Serial No. 403,924.

upper row only, as showr'i, having inwardly bent ends 19 to engage'therings 17, and each link'of these rows having an opposite closed Eachlink 22 of such rows 18 of spaced links has its opposite sides or arms20 bent over at 23 so as to form hook-shaped eyes 2 1-. The oppositeclosed end of each link 22 is formed with a contracted engaging portionor loop 25 which is connected with the straight poi tions 20 of the armsor side members by means of inwardly bent or bowed diverging portionsfor the purpose of providing a narrow or contracted throat 2?.

Rows 28 of other kinds of links alternate with the rows 18, and thelinks of alternate rows are arranged in staggered relation with respectto the links of the rows between them. Each link 28 has a main extendedbody 29 formed with two spaced loop portions 230 which form throats 31.The arms or side of the connec ing portion formed by the body 29, areformed with outwardly bent portions and the ends of the arms are turnedOver at 33 to provide hook-shaped eyes 34-. It will be noted that thewidth of the space between the eyes 3 1 is greater tl an the distancebetween the inner ends of the arms of each link 28, which is due to theoutward divergence of the portions of the arms. By bending the arms ofeach iink 28 in some such manner, as at 32 the arms of the link are morerigid in direction from one arm towardsthe other arm; that is, the saidarms are stiffer than would otherwise be the case in. a direction in theplane of the entire link 2S. It will also be noted that the eyes 34.-are substantia ly parallel with earl other, along lines beyond theendsof the i '3. bod

row. 18 is similarly engaged by two arms of two links 28, 28, and so onin that direction across tiie fabric. The links of each row 18 extend inone general direction from side rail to side rail, and the alternatingrowsof the dissimilar links 28 extend generally transversely to thegeneral direction of the links.

alternate with rows'of links -28 of the other kind. The arms of thelinks 28 extend in the same general (-lirectionv as the links l8,"andthe links of any two adj'acent rows are in offset relation in one row tothe other row.

When suitable tension is placed upon the so-built-up fabric it will beheld quite taut by means *of the tensioning springs 15, 16, with whichthe links are suitably connected. Other springs 35, 36 are at the ends:of th side rails 12, 13 for tensioning in the usual manner the borderlinks 37, 38. T e border links 37, 38 finish the fabric and a time givethe necessary stiffness to the fab ric in a direction lengthwise of theside rails 12, 13.

"While the construction illustrated and described produces a more orless rigid structure it is not too rigid to allow of the desiredflexibility of action. In this connection it will be noted that theinward bows 26 of the links 22 -1nake them more rigid than otherwise,due to the fact that the inwardly bowed portions 26*are bent in theplane of the link 22, in this respect functioning somewhat similarly tothe outward bends 32 of the other links 28. Also it will-be noted thathe location. or fixing of the eyes 34 0f the links 28 in position inthe closed ends of the links is rendered moredefinitcand certain byi'easonmf the contractedthroats 27 of the links 22; and it will also :bein, d that the eyes oft-he links 28 are substa-u 'irlly parallel, andthat where these eyes of two separate adjacent links 28 engage in anyone threat 2?, they'bear mutually one on the other for some distance, soas to render these connect-ions more reliable. The parallel bearingsurfaces of the arms of'thel nks thus contribute to the general firm-nas or steadiness of the wire fabric in its own plane, while at thesainetime the fabric is su iliciently resilient for the intended purpose. Inother words, the bends at the cndso'fthe diverging portions 32 tend tostiffen the arms of'each -link28 without detracting from the desiredresili'encyof the fabric or of-the arms in'their own plane, and' thedivergence of said portions 82th-us' aifor'ds a firmer bearing relationbetween the-eyes :34: than would be the same have longer arms. In otherwords, the links 39 and 40 are of substantially the same or co- .equallength in the direction-of their arms.
